You have asked this question in one form or another several times.
If your kid gets an engineering job in the U.S. after completing an engineering degree, he will be able to support himself.
He needs to attend an ABET accredited engineering program.
Where does your kid want to live after college? India? Here?
You can’t afford the UCs and you likely won’t be able to get instate status for tuition purposes. Plus…you say your income is $50,000 a year…so really…the UCs will not be affordable regardless.
